Answer:
The correct answer is The equilibrium constant for this reaction changes as the pH changes.
Explanation:
The equilibrium constant of a reaction depends of pH and viceverca.There is a equation that link pH with equilibrium constant Ka(for assumption).The equation is given below,
pH=pKa+log[A-/HA]
where[A-] is the concentration of conjugate base and [HA] is the concentration of conjugate acid.
Mixture. Mixtures can be both heterogeneous and homogeneous. Heterogeneous mixtures are mixtures that don't have a fixed composition, meaning that if you take smaller samples from two different parts of a larger sample, the ratios of the substances will differ.
Answer:
Pioneer species
Explanation:
Pioneer species are organisms that are first to colonize and area that is barren, or an area that was heavily disrupted. It could have been disrupted by natural disasters like volcano eruption or a flood. These organisms can grow on bare rock, which (with some help from wind and water) weathers the rocks and create soil. The soil formed eventually allows other forms of life, like plants to move in the area.
